Instantiation

Let’s break down what “instantiated” means in C#.

---

📌 1. Definition

• Instantiation is the process of creating a concrete instance (object) of a class.

• A class is like a blueprint; instantiating it produces an actual object in memory that you can use.

---

📌 2. Example

// Class definition (blueprint)
public class Person
{
    public string Name;
}
 
// Instantiation: creating an object
Person p = new Person(); // p is an instance of the Person class
p.Name = "Alice";
Console.WriteLine(p.Name); // Alice

• new Person() → instantiates the class Person

• p → now holds the object created in memory

---

📌 3. Key Points

1. Classes themselves are not objects → you cannot access fields or call instance methods on a class without creating an instance.

2. Instantiation creates the object in memory and allows you to use its members.

3. Constructors are called automatically during instantiation to initialize the object.

📌 4. Analogy

• Class → blueprint for a house

• Instantiation → actually building the house from the blueprint

• Object → the specific house you can live in

---

✅ Tip:

• Think: “Instantiation = creating an actual object from a class.”

• Every time you use new ClassName(), you are instantiating that class.
